What motor driven surface grinder with power feed *doesn't have* automatic reversing in X and adjustable auto feed step in Y? Even ones 100 or so years old had features like adjustable X travel stops. I'd bet there were grinders with Y travel stops so an operator could set it and forget it, then come back later to crank the table back on the Y axis, turn the spindle down a bit then set it off on making the next pass.

I would rather have motors - maybe a retrofit someday. The issues with hydraulic are power consumption but the pump and leaking oil because it's old. _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
